Reality show couple, Rob Mariano and his wife Amber are expecting their FOURTH child together, and they announced it in the most HIGHlarious way!

After having three girls, Lucia Rose, 4½, Carina Rose, 3, and Isabetta Rose, 20 months, we guess they decided to continue their brood as Boston Rob, who competed on Survivor and The Amazing Race, posted the AMAZING news himself on Twitter, writing:

"Their whole family was around to support them. Evan was very emotional and loves Ashlee so much. He did not leave her side and wanted to go through this with her every step of the way. He can't wait to be a dad. He would do anything for Ashlee and now this baby girl. Ashlee is doing great and can't wait to get home to to be with her family."

No other details have been divulged about their newest family member, but we're so glad to hear Ash is healthy.

Hopefully it's not too long before the family shares a pic of their little bundle of joy!
